Need tooling/workflow to create ShEx JSON files from ShExR (i.e. Turtle) encoding of same

[danbri]

At Google we're looking into publishing .ttl but the JS tools here need ShEx in JSON(-LD) form.

I believe everything is in the shexjs codebase as exposed at http://shex.io/webapps/shex.js/doc/shex-simple.html somewhere, @ericprud is considering API possibilities.

In the shex validator (not schemarama, to be clear, but the tinyurl in prev. entry in this issue), ... remove the querymap section, make sure there's still something to validate, and when you validate there will be shexj at the bottom of the page:

@ericprud adds that behind the scenes the flow is more like:

ShExR and ShexJ -> ShExC, ShExC -> ShExJ

In raw form we get this:
